mormonster 

A desciple of the mormon faith who trolls neighborhoods throughout the day, going door-to-door in an attempt to recruit non-believers

McMonster 

Someone of large physical size who eats at McDonald's frequently.

We were walking out of McDonald's, when, suddenly, a McMonster driving a Ford minivan almost ran us over trying to drag race out of the drive-thru!
